Pure Natural Mid-Brown Gloss Toner with Built-In Vegan Keratin Bonder
Danger Jones Gloss Toner with Bonder in shade 4-0 Natural delivers a pure, clean natural mid-brown result with no directional tone — making it one of the most versatile and essential shades in the Danger Jones Gloss Toner range. Use it alone to refresh faded colour, add richness and gloss to natural brown hair or blend grey seamlessly into a mid-brown base — or intermix it freely with any other Danger Jones Gloss Toner shade to soften intensity, adjust depth or create a more personalised colour outcome. No developer required. Find it alongside other Danger Jones Gloss Toners in our full range.
The Versatile Neutral Every Colour Kit Needs
A pure natural shade with no underlying tone is one of the most useful shades in any professional toning system. Shade 4-0 Natural works as a standalone clean mid-brown gloss, a grey blending base, or an essential mixing shade that dilutes vibrancy and adjusts depth across the full Danger Jones Gloss Toner range. The creamy consistency makes it easy to apply evenly and blend smoothly with any other shade for seamless colour melting and bespoke colour combinations.
Vegan Keratin Bonder, Chia Oil and Apple Cider Vinegar for Conditioned, Shiny Results
The built-in Vegan Keratin Bonder penetrates deep into the hair structure to protect and strengthen during toning, reducing breakage and leaving the hair noticeably more resilient and conditioned after the service. Chia Oil protects the natural result from premature fading and Apple Cider Vinegar seals the cuticle for a polished, healthy-looking shine. The zero lift acidic formula at pH 6.7 deposits pure natural tone with no lightening action for safe, controlled results on brunette, mid-brown and grey-blending services.
How to Use Danger Jones Gloss Toner 4-0 Natural
Apply to clean, damp or dry hair without mixing with a developer. Leave on for the desired processing time before rinsing thoroughly. Blend freely with other Danger Jones Gloss Toner shades to create custom colour combinations and personalised toning results.
